Abstract
Se describen técnicas para llevar a cabo el control automático de la ganancia. En algunos aspectos, el control de la ganancia se llevo a cabo con un aparato que tiene un convertidor de analogico a digital (ADC, analog-to-digital converter) y un amplificador digital de la ganancia variable (DVGA, digital variable gain amplifier), estando el DVGA configurado para recibir una senal digital desde el ADC, teniendo el DVGA un procesador configurado para calcular una ganancia mediante la utilizacion de un logaritmo de base n basado en la potencia de la senal digital emitida desde el ADC, estando el procesador además configurado para aplicar la ganancia a la senal digital.
